2 Claims.

This invention relates generally to the art of hair dressing, andparticularly to an improved form of hairpin.

The main object of this invention is to provide an exceedingly simpleand el'icient means for preventing the loss or accidental dislodgementof hairpins after they are once placed in position in the hair.

The second object is to provide a hairpin of the class described whichwill be inexpensive to manufacture, easy to apply and remove, and notinjurious to the hair or uncomfortable to thek wearer.

These and other objects will become more apparent from the specicationfollowing as illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation of a hairpin equipped with my improvement.

Fig. 2 is an enlarged fragmentary View showing a side elevation of thepreferred form of the device.

Fig. 3 is a section taken along the line 3 3 in Fig. 2.

Fig. 4 is a view similar to Fig. 2 showing how the barb lies down when apull is exerted against the pin greater than the force required toinsert it.

Fig. 5 is a fragmentary View showing a modified form of the device.

Fig. 6 is a transverse section taken along the line 6 6 in Fig. 5.

Similar numbers refer to throughout the several views.

Referring in detail to the drawing, there is shown a common form ofhairpin'll) whose side `members II may or may not be waved, as is thecommon practice. My improvement on the commonly used existing type of.pin consists of a flexible barb I2, which is preferably natural orsynthetic rubber and a part of a tubular section I3 and inclined withrelation thereto, it being similar parts desirable to have the base I4of the barb I2 somewhat removed from the end I5 of the tubular sectionI3 in order to provide a hair engaging socket I6, and prevent the hairfrom being caught in the above junction of the members II and I3. Thetubular section I3 is either vulcanized to the member I I orfrictionally held thereon. In the form of the device shown in Figs. 5and 6 a strip of rubber or flexible material I'I is formed into theshape of a U, Whose sides I8 and I9 are inclined with relation to thehairpin 20., It is desirable to coat the side members 2I with anadhesive 22 for the purpose of positoning the members I8 and I9 andagain for the purpose of preventing hair from becoming caught in theacute angle between members I9 and 2 I.

While only one barb is illustrated in use on a single pin, it is obviousthat more can be employed if desired without departing from the spiritof this invention.

While I have thus illustrated and described my invention, it is not myintention to be limited to the precise form shown herein but I do intendto cover all such forms and modications thereof as fall fairly withinthe appended claims.

What I claim as new and desire to protect by Letters Patent is:

l. A rubber barb for hairpins consisting of a perforated body having alaterally extending barbed portion inclined with relation to the axis ofthe perforation in the barb.

2. The combination of a barrel shaped rubber body having a cylindricalopening formed therethrough along the axis of the body, a U-shapedhairpin having one of its legs projecting through said body and aflexible barb projecting from one side of said body and pointing towardthe closed end of said pin, said barb forming an acute angle withrelation to the closed end of said pin.
